Lu Chen, the proud son of Nancheng No. 1 Middle School, a god of learning and the school's idol, was tied to a "trouble" due to family pressure. Su Wan, due to family changes, fell from a top student to a taciturn "problem student", a loner and a marginalized person on campus. A "contractual love" in which each takes what they need forcibly binds the two: Lu Chen needs Su Wan as a shield to deal with Shen Qingya, the marriage partner arranged by the family; Su Wan needs the "protection" and high remuneration provided by Lu Chen to pay for her mother's high medical expenses.
However, under the contract, sincerity quietly grows. Lu Chen saw the softness and tenacity under Su Wan's hard shell, while Su Wan felt the unknown tenderness and loneliness under Lu Chen's cold appearance. As the relationship between the two gradually warmed up, Shen Qingya, the campus goddess who had coveted Lu Chen for a long time, noticed the clues. Together with her jealous classmates, they began to spread rumors and create misunderstandings in an attempt to expose the truth about the "contract" and destroy Su Wan. At the same time, the Lu Chen family put pressure on him to end his "nonsense" and marry with the Shen family.
Su Wan's inner wall built due to past trauma, Lu Chen's dilemma between family expectations and true emotions, and the fatal secret of the "contract" that could explode at any time, put this relationship in danger. Lu Chen must make a choice under the pressure of a countdown: should he obey the arrangement and preserve the family's interests and surface peace? Or should he break through the shackles of class and rules and bravely protect the unique tenderness hidden in his evening breeze? This is a counterattack journey about growth, courage and true love.
Concept: This is a world that follows the rules of real society and has no supernatural powers. The core rule is: academic performance, family background and social relationships profoundly affect the campus ecology and future path of teenagers
